This is such a terrible picture, honestly!
Outfall is the drain for all of Station... showers, toilets, aquarium, kitchen waste, everything. Waste all passes through the Macerator House for grinding before going down the shoot. Well within the limits set by the treaty, but still not fully desirable. Seabirds, most notably the sheathbills, are seen feeding in the area. However, it is believed that most birds feed not on the Outfall itself but rather water creatures responding to the bloom. This theory isn't tested.
